Can I Change the Oil Filter Every Other Oil Change?
2 Answers
Changing the oil filter every other oil change is not recommended. Below is relevant information about engine oil: Introduction: Engine oil, also known as engine lubricant, with a density of approximately 0.91×10³ (kg/m³), serves multiple functions for the engine including lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption. It is often referred to as the "blood" of a car. Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of lubricants, determining their fundamental properties, while additives compensate for and enhance the performance limitations of the base oil, providing certain new characteristics, making them an essential part of lubricants. Classification: Engine oils on the market can be broadly categorized into mineral oils and synthetic oils based on their base oil composition.
I used to wonder if I could just change the oil filter once during an oil change. I tried skipping it twice, and the engine noise noticeably increased. Upon inspection, I found the filter clogged with sludge, nearly damaging critical components. The filter's job is to trap impurities in the oil, like metal shavings and dust particles. If you don't replace it each time, the new oil gets contaminated, drastically reducing lubrication effectiveness, accelerating engine wear. Short-term effects include higher fuel consumption; long-term, it can lead to cylinder scoring or bearing failure. Most car manuals recommend replacing the filter with every oil change. A filter costs just a few bucks, whereas engine repairs run into thousands. In the long run, skimping on this small expense carries huge risks and isn't cost-effective. My advice: make it a habit—swap in a fresh filter with every oil change to maintain engine health, extend its lifespan, and avoid dangerous breakdowns.
